What Factors Should You Consider When Choosing a Generator for Power Outages?

When choosing a generator for power outages, consider the generator’s capacity, fuel type, portability, noise level, and features such as automatic shut-off and surge protection.

1. Generator Capacity
2. Fuel Type
3. Portability
4. Noise Level
5. Safety Features

Understanding these factors is essential for making an informed decision. Each plays a critical role in ensuring that your generator meets your specific needs during a power outage.

1. Generator Capacity:
   Generator capacity refers to the amount of power the generator can provide, measured in watts. You need to calculate your power requirements to determine the necessary generator capacity. According to the U.S. Department of Energy, average households may require between 5,000 to 7,500 watts to power essential appliances. For example, a refrigerator might need 600 watts, while a furnace can require up to 1,200 watts. It’s advisable to select a generator with a capacity higher than your estimated needs to avoid overloading during peak use.

2. Fuel Type:
   Fuel type is a critical factor because it affects the convenience and efficiency of the generator. Common fuel types include gasoline, propane, and diesel. Gasoline generators are often more accessible but can be less efficient and have shorter shelf lives. Propane is cleaner and has a longer shelf life, making it suitable for storage. Diesel generators tend to be more durable and efficient, especially for heavy-duty applications, but are generally more expensive. Research by the National Renewable Energy Laboratory indicates that the choice of fuel can greatly influence overall cost and operational efficiency.

3. Portability:
   Portability determines how easily you can move the generator during an outage. Smaller, lighter generators are easier to transport, while heavier models often provide more power but can be cumbersome. Depending on your situation, you might prefer a portable generator for temporary use. Many manufacturers offer models with wheels for easy movement. A study by the Consumer Product Safety Commission highlights that portable generators are especially valuable for outdoor activities and emergency backup power.

4. Noise Level:
   Noise level is an important consideration, especially in residential areas. Generators can produce noise levels between 50 to over 100 decibels. Quieter models, often referred to as “inverter generators,” produce sound levels equal to or less than normal conversation. According to the U.S. Centers for Disease Control and Prevention, prolonged exposure to noise levels above 70 decibels can potentially harm hearing. Selecting a quieter generator can minimize disturbances to both your household and your neighbors during outages.

5. Safety Features:
   Safety features enhance the reliability and usability of the generator. Important features to consider include automatic shut-off for low oil levels, carbon monoxide detectors, and surge protection to prevent damage to your appliances. The Consumer Product Safety Commission emphasizes that these features can significantly reduce risks associated with generator use, including fire hazards and carbon monoxide poisoning. Generators with these features may cost more upfront but can provide crucial safety benefits.

Each factor contributes uniquely to the overall performance and usability of generators for power outages. Pay attention to your specific needs to make an informed decision.
